【文章內(nèi)容簡介】 the original main axle around as the datum adjusts, around definite main axle bearing hole proper alignment mon difference in the scope, before and, main bearing hole aperture processing to 。 Roundness tolerance.First should inspect the original main axle slipper the journal section size, because the remainder are not many, must grasp the machining allowance. Before the processing, prepares two 5 morse tapers beforehand the craft center end cover (. Figure 4), inlays separately again the end cover before the main axle in the rear end awl hole, and grinds on carefully the end cover the 3mm center bore, then the arrangement on the precision high lathe, with the double thimble39。s method, carries on the lathe work, according to the bearing in the hole basic hole system39。s request, processes the main axle journal part the taper is 1: 12 (taper 4o4639。19 ) the size 100 requests (request to leave leeway grinding allowance). Simultaneously processes the axis files adjustment thread separately again, in 1 adjusting nut and 2 adjusting blocks, the addendum circle adjusting shim (request filling piece thickness leaves leeway sharpening quantity). Finished, carried on the abrasive machining again to the main axle journal part, met the main axle proper each requirements.Figure 4 before the main axle, bearing meck part transformation3 assemblies and debuggingThe rotation stopping nut makes the end motion to the belt awl39。s bearing inner rim along the main axle coneshape then to realize the adjustment. Namely with spanner tight nut 9, when the hand makes an effort moves the main axle the main axle to be able to rotate automatically for 12 weeks, then explained that front bearing39。s radial clearance has adjusted suitably, otherwise the showing gap oversized or is too small, then screws tight the bolt 8. Rear bearing39。s regulation means and front bearing39。s regulation means are the same. In order to increase main axle39。s rotation precision, when assembly uses “the directional assembly” the principle carries on
